You can’t combine or merge Microsoft accounts, but if you have multiple accounts, you can share your Xbox Live Gold subscription and content on your Xbox One. To do this, make sure that all of your accounts are on the same Xbox One console, and then select that console as your home Xbox. Now you can share your Xbox Live Gold subscription with anyone else who signs in on your console.
